CTD's composites in space
TEMBO®, CTD’s Elastic Memory Composite (EMC) material, has blasted into orbit aboard the Space Shuttle Discovery. The EMCH experiment, sponsored by the Air Force Research Laboratory, will validate operation of TEMBO® EMC hinges in zero gravity. Astronaut Sunita Williams, Expedition 14 Flight Engineer on the International Space Station (ISS), will operate EMCH, which is scheduled to remain on the station for 18 months.
TEMBO® EMC Hinges were developed for deploying solar arrays, communications, and optical systems in space. Combining carbon fibre reinforcement and shape memory polymers, TEMBO® composites replace complex mechanical deployment systems with simpler and lighter ones.
As a result of the mission, traditional size and scaling barriers for spacecraft deployable systems could vanish. Future mission concepts requiring large lightweight structures are now near realization. Based on TEMBO® materials, CTD is developing the RAPDAR (Roll-out and Passively Deployed Array), a new lightweight deployable solar array that can provide more power to a satellite than current solar arrays. CTD is also using TEMBO® materials to develop large aperture, high frequency reflectors that provide more bandwidth at a lower cost than current reflector designs.
